1 claim. (cl. iis-104.31y

erated by a single person for cleaning the drain pipe in a building. Y

Another object of the invention is the construction of a novel persuaderthat can be quickly applied to a snake, whereby the plumber can greatlyincrease the rotary movement of the.

snake for removing an obstruction in a drain pipe.

A still further object of the invention is the invention is theconstruction of an efcient apparatus wherein a novel persuader isemployed in conjunction with a snake and an efficient handle for theremoval of an obstruction in a drain pipe.

With the foregoing and other objects in view, this invention comprisescertain novel constructions, combinations, and arrangements of parts aswill be hereinafter fully described, illustrated in the accompanyingdrawings, and more particularly pointed out in the appended claim.

In the drawings:

Figure 1 is an enlarged longitudinal sectional View of a drain pipe,showing in elevation an apparatus constructed in accordance with thepresent invention.

Figure 2 is a top plan View of the sectional persuader, while Figure 3is a longitudinal, vertical, sectional view of the same.

Figure 4 is a transverse sectional view, taken on line 4-4, Fig. 2, andlooking in the direction of the arrows.

Figure 5 is an enlarged sectional view, taken on line 5-5, Fig. 1, andlooking in the direction .0f the arrows.

Referring to the drawings, in which the preferred embodiment of thisinvention is illustrated, I designates a drain pipe and 2 is theobstruction therein. Integral with the drain pipe I is a waste pipe 3,as well as a cleanout hub 4. A plug holder 5 is in the cleanout hub 4.

A coiled snake 6 is provided which has on its inner end a spiral 1.

The persuader 8 comprises a primary section 9 (Fig, 4) and an auxiliarysection I0. Screw pins Il are threaded into the primary section 9. Thesepins have their inner ends smooth so that they will freely slide in thepin-receiving apertures` I2. These pins Il keep the two sections 9 andI0 in correct position for causing the screw threads I3 to registerprior to threading the persuader 8 into the plug holder 5, Fig. 1. Thesurface of the outer end of the persuader 8 has fiat portions on itsperipheral surface, so as to afford an excellent grip for a monkeywrench, or the like, when the operator is screwing the persuader intothe plug holder 5. The persuader is grooved at I4, Fig. 3, to receivethe coiled snake 6. These grooves I4 act similar to screw threadsockets.

On the outer end of the snake 6 these is formed an annular groove l5. Ahandle I6 is placed on the outer end of the snake 6 and a locking screwI'I is on the handle, whereby when screw I'I is screwed inwardly, theinner end of the screw will engage groove I5, and by tightening screwII, the handle can be held rigidly on snake 6. Interposed between thepersuader 8 and the handle I6 is a free grip I8, which revolves on thesnake 6. The handle I6 is provided with a stub shaft I9 that has on itsouter end a head 20. On the stub shaft I9 is a free rolling grip 2|. Torotate the snake 6, the operator grasps the grip I8 with one hand andgrip 2| with the other hand, and by rotating the handle I6, the snakecan be either threaded into the drain pipe I or removed therefromsufficiently to enable the plumber to easily remove the entire apparatusfrom its operating position.

In operation, the plumber or operator usually threads the snake into thedrain pipe as far as they can easily do so, prior to applying thepersuader 8 to the snake. Then when the movement becomes hard on thehands, the persuader 8, by reason of its sectional structure, can beclamped on the snake and then screwed into the plug holder 5. The handlestructure can be also quickly attached to the snake. One operator canmanipulate this apparatus and can secure excellent results.

By reason of the powerful rotary action that can be obtained, the snakewill be forced past any obstruction in the drain pipe, thereby removingthe obstruction and producing a clean drain pipe. The spiral I of thecoiled snake Ii will efiiciently pass around corners and angles and badspots in the drain pipe.

To remove the apparatus from its assembled position, Fig. 1, the screwI1 can be loosened, whereupon the handle structure can be quicklyremoved from the snake 6, and then the persuader 8 is removed from theplug holder 5, whereupon the interlocking sections can be quicklyseparated and then the snake 6 can be easily pulled out of the drainpipe. By the sim- 3 plicity of all of the parts mentioned, this removingof the apparatus can be quickly accomplished.

While I have described the preferred embodiment of the invention andillustrated the same in the accompanying drawings, certain minor changesor alterations may appear to onerskilled in the art to which thisinvention relates 'dur'- ing the extensive manufacture of the saine, andI, therefore, reserve the right to make such the scope of the appendedclaim.v

What I claim is: n v As a new article of maiiuatuie, a `ti'ifil "for 10,y changes or alterations as shall fairly fall within cleaning wastepipes, comprising a 'cylindrical "15 persuader of substantially the samethickness from end to end, said persuad'e'rliei diameti'ifcally splitthroughout its length and comprising a primary section and anauxiliary'seet'ioii, said sections provided with flat contacting facesthe `greater part of theirfdianeter, fsaid aux iliary section providedWithtwo pin=receiving apertures, said primary section 'provided with twothreaded apertures registering with sain Y pin-receiving apertures ofsaid1auxiiisuy sentan, pins slidably mounted in said pin=receivingapertures 'andrthreaded at one of their 'outeriends in said threadedapertures, said persuader being externally screw-threaded o'neh'alf diits length, said persuaderheyonditsserew threads and at on'e'end havingiiat portions-on its peripheral surface for receiving a monkey Wrench,said sections of said persuader being helica-lly grooved internallythroughout their lengths to act similar to screw thread sockets. acoiled snake threaded through said persuader and in engagement with saidsockets, and a handle secured to the outer end of said snake.
